Gently Supporting Your Fertility Journey
We'll gently support you both on your journey to parenthood.
Ninkatsu Style is a brand born to support all couples who wish to have children, gently accompanying them on their fertility journey.
In today's world of dual-income families, delayed marriage and childbearing, a high-stress society, and diverse family values and lifestyles, it is challenging to solve fertility challenges through effort alone.
"We can't seem to get the timing right for natural conception..."
"Physical reasons make intercourse difficult..."
"We want to try fertility methods at home before visiting a clinic..."
"We want children, but we're experiencing sexual dysfunction..."
In response to these concerns, we developed the "Prement Syringe," which allows couples to try the syringe method at home. We were the first in Japan to commercialize and sell this product. We remain committed to supporting every couple's fertility journey with compassion, helping them achieve their dream of parenthood.
Pioneer of Syringe Method Kits

"Prement Syringe" is the syringe method kit we developed and were the first to commercialize and sell in Japan. Since its launch in 2016, we have sold a cumulative 2.5 million units and received over 1,000 pregnancy success reports from our customers.
Our products are now used not only by couples seeking to conceive, but also by fertility specialist clinics, wellness centers, acupuncture clinics, herbal medicine pharmacies, and hospitals in Hong Kong and beyond.
